PETER A. OASSIDY, OF WASHINGTON, DISTRICT OF COLUMBIA.

IMPROVEMENT IN MACHINES FOR CUTTING LEATHER, &c.

Specification forming part of Letters Patent No. 179,645, dated July 11,1876; application filed May 9, 1876.

To all whom it may concern:

Be it known that I, PETER A. OAssIDY, of

Washington, in the District of Golum bia, have invented a new and usefulMachine for Outting Vellum -Oloth, Leather, Paper, or other similararticles into strips, which invention is fully set forth in thefollowing specification, reference being bad to the accompanying drawings.

The object of my invention is to rapidly and cheaply cut into stripsvellum-cloth for mending muster-rolls, documents, abstracts, leather forboolrbinding, harness making, &c., and paper, or any similar article.

To accomplish this I provide a cutter-holder or gage furnished withanumber of knives, operating upon and in combination with a bed uponwhich the article to be cut into strips is fastened, the bed having anumber of parallel grooves to correspond with the cutters, and upon oneside a guidepiece, upon which fits a groove in the cutter-holder, whichso operates as to cause the cutters to move in a straight line, and toconstantly retain their cutting-edges in the grooves.

in the accompanying drawing, Figurel is a perspective view of mymachine, showing a piece of vellumeloth or other article to be cutfastened on the bed. Fig. 2 is a section of the cutterholder, showingthe method of fastening the cutters.

The bed-piece A may be of any convenient length, havin gin its uppersurface a number of parallel grooves,a b c d 0, made at such distancesapart asitis desired that the width of the strips to be out should be.Upon one side of the bed-piece is a guide strip, K, over which fits acorresponding groove, f, at one side of the cutter-holder 1*. Thecutter-holder F has secured therein the cutters A B C D E, which areplaced at such a distance apart as to correspond with the grooves inwhich they move. The cutters are caused to movein. a straight line, andtheir cutting edges to remain constautly in the grooves, by theguidestrip K and the guide-groove f in the cutter-holder.

The cutter-holder is also provided with a handle, L, by which it may begrasped by the hand, and moved over the bed in the operation of cutting.

The cutters are made with two cuttingedges, ij, Fig. 2, so that theywill cut, when moved over the bed, in either direction, and are alsoWedge-shaped, and may thus be readily fastened into the holder byinsertion into the tapering sockets, as shown in Fig. 3.

The bed-piece is furnished with pinsk l m, (shown in Fig. 1,) to'holdthe material and keep the edges even and together when more than onethickness of cloth or other material is being cut.

The machine may have any convenient number of grooves and correspondingcutters, and they can be placed at any distance apart to correspond withthe width of the strips to be cut.

In case the material to be cut is thin, like vellumeloth or paper, anumber of thicknesses may be placed on the bed and cut at one time.

I claim as my invention- 1. In a machine for cutting vellum -cloth,leather, or other similar materials, the combination of a cutter-holder,F, carrying a number of knives, A B O D E, and having a guidegroove, f,with a bed, A, having grooves a b c d 6, corresponding with the cutters,a guidestrip, K, and holdingpins 76 l m, all to operate in the mannerand for the purpose de scribed.

2. The cutters A B (J D E, having two cuttingedges, and wedge shaped invertical cross-section, in combination with the cutterholder F, havingtapering sockets, into which the wedge-shaped cutters fit, and aguidegroove, f, operating upon a bed, A, having grooves a, b c d 0,corresponding with cutters, guide-strip K, and holding-pins k l m, allto operate in the manner and for the purpose described.
